    Testing the Unification Model for AGN in the Infrared: are the obscuring tori of Type 1 and 2 Seyferts different?
    I will present new mid-infrared imaging data for a sample of ~20 nearby Seyfert galaxies obtained with T-ReCS and MICHELLE on the Gemini Telescopes at...

    Tests for the Expansion of the Universe
    Almost all cosmologists accept nowadays that the redshift of the galaxies is due to the expansion of the Universe (cosmological redshift), plus some Doppler...

    The "Vanishing and Appearing Sources during a Century of Observations" (VASCO) project: a status update
    Traditional Searches for Extraterrestrial Intelligence (SETI) use large radio telescopes to look for artificial signals from specific stars. In the era of large...

    The 1D plane-parallel PDR model and its application
    A simple model using the balance of photodissociation assuming a one-dimensional plane-parallel model yields total hydrogen volume densities for a column of...

    The abundance of primordial helium: a keystone in our understanding of the Universe
    Primordial helium might seem to be just a tiny piece in our understanding of how the Universe was born; still, it is a piece that must fit in if we are to...

    The anomalous microwave emission in our Galaxy
    The anomalous microwave emission (AME) is an additional diffuse foreground component, originated by an emission mechanism in the ISM different from the well...

    The basal flux and the solar cycle variations
    In the first part of the talk, I discuss the chromospheric activity of quiet Sun. The so-called basal flux, the minimum chromospheric emission of main sequence...

    The binary population in Galactic globular clusters: theory versus observations
    I present the first results of a long term project devoted to the study of the evolution of the binary population in globular clusters. Using deep ACS@HST...
